Any subwoofer you pick, you'll have to calibrate your system and adjust the levels.

Question:
Just how good are these passive crossovers? I mean, if I wanted to use active crossovers instead, would I be throwing away a lot of what I'd be paying for?

You could but you'd need expensive test equipment, muiltiple amplifiers, tons of DSP and a lot of time.

JTR Captivator $999 plus a pro amp to run it would run you around $1300. Another option would be a pair of MFW-15's. Like Jeff said, lots of subwoofers would sound great as long as you integrate them well.

20-25" would put the coaxial at ear height depending on the height of the listener. The center of the coaxial is 13" from the bottom of the speaker.

Since I have a non acoustically transparent screen, I put all three speakers just below the screen vertically with the coaxials mounted on top. This puts them at about a 27" height because of a raised area of the floor that I have them sitting on. I have them slightly angled up so that they are facing the listeners directly.

You could put them behind an acoustically transparent screen and not have this issue or place the left and right to the side of a display at ear height.

Thanks for the info. I just need to convine the wife we NEED these speakers.

I understand the multiple amps, DSPs, and of course lots of time - this is a hobby :-) - but I'm not sure I'm understanding the tons of test equipment.

If I used something like the Digmoda, I'd need a computer - which I have - and a microphone. What am I not figuring it here for test equipment?

Thanks!

Could power a Captivator with something like the Daytone SA1000

I use an OEM version of that amp for many of my clients, and it works incredibly well for the price.

Will this be a floor standing speaker with one 12" coax driver and four 12" bass drivers Jeff? That would be something really special!

The Quintuple uses 8" drivers, for the aesthetic conscious, now on pre-order and will start shipping middle of next month. Check the JTR forum for details.

Do you have any images available Jeff?

Thanks for the reply Jeff. Would you ever consider a quintuple with 12" drivers?

Can't believe I didn't see these when I visited. The different finishes sound awesome.

In gregs case he was looking for more midrange punch then what the triple 12s offer so being space is limited he down sized to triple 8s to make room for the growlers. So his center tripple 12 will match up better with the full range of the growlers and 888s together. This really is the ultimate setup because your dedicated sub will take care of the low end say 10hz-30hz and the growler will take care of the mid bass 30hz-80hz and the 888s will take off 80hz up. This is how you get that mid bass slam that kicks you in the chest.

I'm going the same route because I really like stong mid bass also and will have my 12s crossed at 50hz-60hz and the mid bass sub will take care of the 30hz-60hz and 5 18in mal-x driveing my lowend in large ported boxes.

This is really the only way to go if you want strong full range sound with out any weak spots.

The mid bass chest thumping u speak of is exactly what I am looking for, so for starters I am going with an 8ht for center along with a growler and a submersive. Later I will replace my pair of BP2002's with 8's when I get some more money. (Who really needs a new kitchen.)

My question is how do I set the x-overs between my fronts, the growler and the submersive? My equipment is a denon 3808 and an emotiva xpa3.

Will the xpa3 drive the growler and the 8ht while the denon 3808 pushes the 2002's set to small?

Thanks,

Wes

I have read from users as welll as Mark Seaton that the Submersive is very strong in the midbass so you would not be making use of its full potential if you do a hybrid LFE so to speak. Now if your running the Growler in conjunction with your fronts you can use a Behringer DCX2496 (on the cheap) or a DBX Drive Rack or some others to implement. In that configuration your receiver will basically see large fronts and cut off wherever the Growler starts to roll off on the bottom.

I agree with GPMBC and would add that you may be over thinking this and setting yourself up for an integration nightmare. The Submersive can easily handle the <80hz frequencies that the T8's won't cover and give you plenty of midbass slam.

I see no reason for a Growler/Submersive combo that relegates the Submersive to a narrow <46Hz range. If it's mid bass you are after, get T12HT's rather than T8's.
post #225 of 18423
I'd like to know more about the upcoming Quintuple. Will it be another woofer added to the top and bottom of the T8 or will it be a traditional tower with 4 woofers on the bottom and the mid/tweeter on top? Are there any pictures available of prototypes?

My handy work isn't picture worthy so I'll get some pictures up next week after I get the first off the CNC.

just wondering what kind of bannana plugs I can use with my 12s that have the pro binding post.

I'm guessing people don't mind seeing an early prototype, but we'll wait if we have to.

Any bannana that the positive and negative aren't attached to each other.

Can someone recommend a few amplification options for JTR speakers? I am guessing they are a pretty heavy load , especially if cranked . And if I buy some they are definately gonna get used hard.

thanks
post #234 of 18423
Try a Behringer EP-2500 for a pair.
post #235 of 18423
I agree, the Behringer is good for HT since it has a good power to price performance ratio. But it also has some fan noise so depending on where it is, that might be a consideration.

I tell my clients to look for used Earthquake Cinenovas (600wpc @4 ohms with LOW noise and no fans) also used ATI's and ADCOMs in the 300wpc range work well.

For those interested in having the best "audio/music" performance from JTR, I have been steering my clients to the Wyred 4 Sound offerings.
post #236 of 18423
The Earthquake was nice as well. For the price the Behringers are unbeatable, just noisy fans. I do have them in a separate room. I will most likely get Ada gear myself. The new HD processor and maybe some amps. The MPA-501 is a beast.

Hi Allan,

This was exactly my upgrade path; I believe I was one of Jeff's early adopters and needless to say, I've had Jeff's product behind my screen ever since.

Hope you enjoy.

Larry

I was able to get a really good deal on QSC RMX850's - running one for each channel in Bridged mode.
post #239 of 18423
I have a bonus room above my garage that has been turned into a HT room. I too am interested in a JTR package with pro amps (price vs power), but the noise created by the fans would make it difficult to enjoy a movie.

I have access into the attic through the room, If I were to place the amps in the attic and run cables into the room would I encounter any amp problems?

Also, the wyred 4 sound amps are very intriguing, they have received rave reviews. Would the 5 X 550@4ohms be plenty to drive either the triple 8 or triple 12 in a 13W 20L 8H room being that they both have 95 + sensitivity. Not going for SPL records
post #240 of 18423
I have an Emotiva XPA-5 amp driving my Triple 12LF LCR in a 24x34x9 room and it rocks.
